I started doing this after getting a dozen Vodafone marketing calls. Except instead of just leaving the phone off-hook, I said "please hold while I transfer you" and then treated them to an endless random shuffle of Never Gonna Give you Up, Friday, Trololo, Caramelldansen, and Nyan Cat, played via a voice modem.

They stopped calling after they got that a couple of times.

Submission + - Container ship breaks in two, sinks

Cliff Stoll writes: Along with 7000 containers, ship MOL Comfort broke in half in high seas in the Indian Ocean. The aft section floated for a week, then sank on June 27th. The forward section was towed most of the way to port, but burned and sank on July 10th. This post-panamax ship was 316 meters long and only 5 years old. With a typical value of $40,000 per container, this amounts to a quarter billion dollar loss. The cause is unknown, but may be structural or perhaps due to overfilled containers that are declared as underweight. Of course, the software used to calculate ship stability relies upon these incorrect physical parameters.

While commenters here will be quick to point out that the font doesn't actually provide protection, you have to realize that there are people who will actually perceive the font as offering protection. Setting the record straight is just as important as recognizing the artistic message behind the act. We can appreciate the intent and the result, but we should also not delude ourselves that it has purpose beyond simply conveying an artistic message.

What's interesting is that this actually enriches the post-modern interpretation of the artwork, rather than detracting from it. Not only does the work demonstrate the superficial rejection of the all-seeing police state, but to those who understand and appreciate the technical aspects of the digitization of data, it also demonstrates deeper opposing meanings that are equally valid:

  • that despite the effort of the common man, it is practically impossible to hide from the panopticon;
  • that the commercialization and publication of a "standard" way to avoid breaches of privacy (i.e. a monoculture of privacy applications, like how so many people turn to 1Password) inevitably lead to breaches of privacy due to the shared central point of weakness; and
  • that, ultimately, the assumption of and reliance on a shallow culture of privacy ("oh, just use PGP and you're safe!") is insufficient.

Google uses ephemeral Diffie-Hellman key exchange for its SSL implementation, as long as the client is modern enough (i.e. everything except IE on Windows XP). That provides forward secrecy. Even if the NSA had the private keys, they wouldn't be able to snoop on anyone's traffic by passively sniffing - they'd have to mount an active MITM attack, and that is much harder to do, and even harder to do undetectably.

My first job was delivering telegrams (by bicycle) in downtown Buffalo during the 1960's.
My Western Union office had its hours posted on the door: "We Never Close". The building's been torn down, so, in a sense, the message turned out to be true.

Here in Berkeley, one of the main drags is Telegraph Avenue and a cell-phone store is named "Telegraph Wireless"

I work in computing; a meter away is a mathematician.

He knows real math: group theory, complex analysis, Lie algebras, topology, and, yes, differential equations. To him, math isn't about numbers ... it's about rigor, elegance, and beauty.

No surprise that his code is rigorous, elegant, and beautiful. When he showed me how to use Cheetah to build templates in Python, he explained things with an clarity and parsimony. In his world, clumsy coding is as bad as a clunky math; a clear mathematical proof is as fascinating as a tightly written function.

This man is the go-to guy for the 100 person business. Soft spoken and never argumentative, his advice and opinions carry weight. I'm honored to work alongside him; not a week goes by that I don't learn from him.

This is the sort of conversation to expect from deniers, and not from actual skeptics.

Regarding whether the accumulation is exponential, maybe step back and take a broader look?

"Whether or not 400ppm has any other detrimental affect other than temperature (which it obviously hasn't driven to Eocene levels)"

You're missing a word. "Yet".

Remember when I said "There is no claim that the system will respond instantly. A system as large as the earth will take some time to warm up." In this thread? No I figured you didn't. Forgetting counterarguments is a specialty you guys cultivate.

Well, I did my best. Go ahead and have the last word if you must.

It's a milestone. Those of us who have been thinking about this a long time once had 400 ppmv in mind as a distant, avoidable future.

As for whether it's been linear, go look. http://en.wikipedia.org/wiki/File:Mauna_Loa_Carbon_Dioxide-en.svg

"Then why compare today's ppm of CO2 to the Eocene and imply that we're headed towards Eocene temperatures?"

Are you really that silly? Falling from a great height onto a cement slab is not the only thing that can adversely affect your health. But that doesn't mean it's good for you!

This is a silly argument. Nobody claims CO2 is the only factor affecting global mean surface temperature.

Anything pre-1970 is a bit beside the point; as the accumulation has been exponential, the forcing was quite small then.

Leaving aside the 1998 cherry-pick, surface temperatures have increased more slowly than expected, but it is not flat. There are at least three explanations on the table other than "climate scientists know less than nothing and therefore there is nothing to worry about".

Since probably nobody will read except you who is not really interested this I'll be brief. 1) El Ninos have been scarcer of late, since 1998. As far as I know it's debatable whether this is a climate change feature or just random. Such a shift will superimpose a one-time cooling on the trend. 2) Heat is accumulating in the deep ocean 3) Increased particulate emissions may be increasing low clouds which provides some temporary masking. The first two are not uncertain to first order. None of these will affect the long term prognosis.

You are reading unreliable sources. I suggest you open your mind to the scientific mainstream before dismissing it.

Well, I doubt it was because of the jeans.

But if it was, you might notice that you had the jeans on for some time before the accident occurred.

This is a strawman argument, though it might not be obvious to you that it is.

There is no claim that the system will respond instantly. A system as large as the earth will take some time to warm up. The energy imbalance is real and measured. There's just some delay in the system. A few decades is a very short time in earth history. Things are already heating up, but what we see is the response to the forcing up to 20 or 30 years ago.
